A device for compressing the abdominal wall and colon to facilitate a colonoscopy.
Examination of the colon is performed for a variety of medical conditions. The colonoscope, inserted into a patient's rectum, contains a fiberoptic imaging device to provide a view of the colon and to assist in making a diagnosis. In addition to an imaging device, the probe may include a device to perform a procedure such as removing growths, such as polyps.
It is often difficult to advance the colonoscope through the entire length of a colon. Portions of the colon may become distended during the insertion of the colonoscope. The imaging device on the end of the probe may remain stationary or move backwards if this condition is encountered. This is a particular problem because portions of the colon, such as the sigmoid colon, are not fixed within the abdominal cavity. To combat this problem, it is common for a nurse or endoscopy assistant to manually compress the abdomen during the colonoscope insertion. External pressure is applied in an effort to support and move the colon. The application of external pressure helps advance the colonoscope by inhibiting the distension of the colon. However, it is common that the assistant not be able to sustain the correct amount of pressure or in the correct area. The inaccuracy and inadequacy of the application of pressure can result in the difficulty in advancing the colonoscope through the entire colon.
U.S. Pat. No. 5,685,321 (Klingenstein) discloses a device and method to facilitate a colonoscopy by externally compressing the colon. The device is a wrap that surrounds a patient's abdomen and has an inflatable bladder to apply force to the patient's abdomen. The inflatable bladder is placed on the wrap so that it covers the lower left-hand quadrant of the patient's abdomen. This placement allows the sigmoid colon to be supported. The bladder may have an additional flap of material stitched to the wrap or may be coupled to the wrap using hook and loop fasteners. The bladder can be repositioned on the belt. The bladder can have a variety of shapes to apply different compressive forces.

It is another object of the invention to provide a method for applying pressure to a patient's abdomen comprising securing a vest about the patient, the vest having a pair of inflatable bladders, aligning the vest on the patient to have the bladders equally distanced from the centerline of the patient's abdomen, and inflating the bladders to apply pressure to the patient's abdomen.
It is yet another object of the invention to provide a method for performing a colonoscopy comprising securing a vest about the patient, the vest having a pair of inflatable bladders, aligning the vest on the patient to have the bladders equally distanced from the centerline of the patient's abdomen, inflating the bladders to apply pressure to the patient's abdomen and compressing the colon, while inserting the colonoscope.
It is an object of the invention to provide a vest that uses inflatable bladders to apply pressure to a patient's abdomen.
It is another object of the invention to provide a vest that applies pressure to a patient's abdomen to compress the patient's colon.
It is another object of the invention to provide a vest that has adjustable pressure applied against the abdomen.
It is yet another object of the invention to provide a belt that is adjustable in girth to fit a patient.
It is another object of the invention to provide a vest that applies pressure to cover the entire colon of the patient.
These and other objects of the invention will become apparent after reading the description of the invention that follows.
In one aspect of this invention of a device for applying pressure to a patient's abdomen, there is provided a vest for encircling a patient having two ends, a centerline of the vest located equidistant from each end. There is also provided at least one pair of inflatable bladders retained by the vest, one bladder of the pair located on each side of the centerline.
In yet another aspect of this invention of a vest for applying pressure to a patient's abdomen, the vest is provided an inner layer and an outer layer, the inner and outer layers joined to one another and having a left side and right side and a centerline equidistant from the left and right sides. Inflatable bladders are also provided and located between the inner and outer layers for applying pressure when inflated. The inflatable bladders comprise at least a first and second bladder, The first and second bladder located equidistant from either side of the centerline.
In yet another aspect of this invention a unique method for applying pressure to a patient's abdomen is provided. The method comprises the steps of (1) securing a vest about the patient, the vest having a pair of inflatable bladders; (2) then aligning the vest on the patient to have the bladders equally distanced from the centerline of the patient's abdomen; and (3) then inflating the bladders to apply pressure to the patient's abdomen.
In the drawings:
FIG. 1 is a view of the device in use on a patient;
FIG. 2 is an exploded view of the device and slip; and
FIG. 3 is a cross-section of the vest about a patient (shown in phantom).
The colonoscopy pressure device 10 is a vest that wraps around the patient. The device 10, as used on a patient, is shown in FIG. 1. The two ends 24, 26 of the vest 11 may be connected to each other to secure the vest 11 about the patient by any known means. Once connected, the vest 11 is tight about the patient. The vest 11 may have rectangular, inflatable bladders 12, 13 that may be selectively inflated and deflated. The bladders 12, 13 may be formed by heat welding two layers 42, 44 of the vest 11 to one another. Also, the bladders 12, 13 may be separately formed and attached to the vest 11 by any other means such as by being stitched into pockets (not shown). As the bladders 12, 13 are inflated, pressure is applied to the abdomen of the patient. Each bladder 12, 13 has a meter valve 15 to slowly reduce the pressure. Pressure maintains the position of the colon to facilitate passage of the colonoscope through the colon.
As the bladders 12, 13 are inflated, greater pressure is applied to the abdomen. The doctor can select the amount of pressure applied by varying the amount of inflation. The placement of the bladders 12, 13 insures the pressure is applied to the correct area of the abdomen. When the center of the vest 11 is aligned with the center of the abdomen, the bladders 12, 13 are in the correct position. The bladders 12, 13 may be separated by approximately one and one half inches on either side of the center of the abdomen to approximately four inches from the centerline as a function of the patient's waist. This is true regardless of the height of the person. The size of the bladders 12, 13 is large enough to cover the entire left and right side of the abdominal wall extending from the rib cage to the inguinal area. For a person 5′8″ and above, the bladders 12, 13 may be approximately ten inches in height and approximately four to five inches in width. For an individual between the height of 5′4″ and 5′8″, each bladder may be approximately six inches in height and approximately three to four inches in width. For individuals 5′ to 5′4″ in height, the bladder size may be approximately five inches in height by approximately two inches in width.
As can be seen in FIG. 2, the vest 11 has a left and right end that are attached to one another about the individual. The two ends may be attached to one another in the posterior or anterior midline. The attachment has to be strong enough so that the vest 11 does not pull apart when the bladders 12, 13 are pressurized. Many conventional connectors, such as hook and loop fasteners 24, 26 (VELCROŽ) are sufficient for this function. The device 10 may be placed within a pillowcase-type slip 30 which may be constructed of any well-known material, such as a soft fabric, for the comfort of the patient. Alternatively, the case may be a disposable plastic sheath. The slip may be disposable for sterile purposes.
The structure of the vest 11 is seen by the depiction in FIG. 3. The vest 11 may be formed of any suitable material by two layers of plastic 42 and 44. The two layers 42, 44 of plastic are joined to one another to form the vest and the bladders 12, 13 are enclosed between the two inner layers 42, 44. The bladders 12, 13 can be inflated by any conventional means, such as hand operated pressure bulbs or a foot operated pump (not shown).
Many alternatives of the invention are possible. For instance, the two ends 24, 26 of the vest 11 can be connected by laces (not shown). In this instance, the laces extend to join or lace together the ends 24, 26. As the laces are tightened, the two ends 24, 26 draw closer to one another to secure the vest 11 about the patient. Also, the device 10 may be a Mae West, but instead of pockets with kapok, there are the inflatable bladders.
While the invention has been described with reference to a preferred embodiment, many modifications and variations would be known to one of ordinary skill in the art without departing from the scope of the invention. The description of the preferred embodiment is not intended to be limiting in any way, but the invention is defined by the appended claims.
